OIL STOVE.

Application filed February j This invention relates to oil stoves, andis particularly directed to a safety valve arrangement for oil stoves.

In oil stoves it has been usual practice to provide some form of burnerfor heating the oil to a gaseous state and thereafter burning it. Itsometimes happens that the supply tank becomes sufficiently heated togenerate excessive pressure with consequent disturbance at the burnerresulting in an enormous pressure or dangerously large flame.

This invention is designed to provide means for overcoming the defectsnoted above, and objects of such invention are to provide a safetydevice for oil stoves which will relieve all pressure in the supply tankwhenever the flame becomes excessive, and which will prevent explosion.of the stove or any damage resulting` from excessive prer`^ sure.

An embodiment of the invention is shown in the accompanying drawings, inwhich 'lhe single figure is a View somewhat diagran'imatic of a portionof a stove showing the supply tank, burner and safety device in theirrelative positions.

Referring to the drawings, it will be seen that a supply tank l for thefuel has been provided which is normally pumped up through the fitting2, so that oil or other fuel is forced through the pipe 8 to the burner,indicated generally at 4. It sometimes happens that the supply tank lbecomes excessively heated through improper manipula tion of theapparatus and, under these conditions, an excessive quantity of oil isfurnished the burner. This increases the size and heat of the iiamewhich again reacts upon the supply tank. This invention overcomes thedangers discussed above in a simple manner.

A pipe 5 leads from the upper portion of the tank l and extends to afitting indicated generally at 6. This fitting is placed in the regionof the burner 4 and is provided with a downwardly or outwardly extendingdischarge pipe 7.

The fitting 6 is provided with a pair of members 8 and 9 which arescrewed together and which receive between them a fusible disk orwafer-like member l0. When the 6, 1926. Serial N0. 86,637.

flame is too great at the burner, sufficient heat is given to thefitting 6 to fuse the disk l0 and to allow the excess gas pressure toblow off and to thus stop further feeding of the fuel to the burner.'This action is wholly automatic and does not require the supervision ofthe operator.

It will be seen that an extremely simple form of device has beenprovided by this invention and one which may be'cheaply and readilymade.

Further, the hazard due to the use of oil stoves is markedly reduced byapplying this invention to the usual types of oil stoves.

Further, the usual types of oil stoves can be very readily and easilyequipped with this protecting device so as to render them automatic intheir action when excessive pressure occurs during the operation of thisstove.

Although the invention has been described the invention may be variouslyembodied and as the scope of such invention is to be determined asclaimed.

We claim:

l. An oil stove comprising a supply tank, a burner supplied from saidtank, said tank being adapted to contain fuel under pressure, adischarge pipe leading from the upper portion of said tank and having afittinf` positicned adjacent said burner, an outlet pipe leading fromsaid fitting, and a fusible menber interposed in said fitting betweensaid last mentioned pipes and adapted to be fused when said burner isexcessively heated.

2. An oil stove comprising a fuel supply tank adapted to contain fuelunder pressure, a burner fed therefrom, a pipe leading from the upperportion of said tankto a point adjacent the burner, a fitting carried bysaid pipe, an outlet pipe carried by said fitting, said fitting being intwo parts, and a fusible disk clamped between said parts.

In testimony that we claim the foregoing we have hereunto set our handsat Milwaukee, in the county of Milwaukee and State of Wisconsin.
